Minimally Invasive Sampling of Mediastinal Lesions

Area of Science:

• Pulmonology
• Interventional Radiology
• Gastroenterology

Background:

• Mediastinal lesions require accurate diagnosis and staging for effective management.
• Minimally invasive sampling techniques have evolved significantly, offering alternatives to surgical biopsy.
• Image-guided procedures are crucial for precise tissue acquisition.

Purpose of the Study:

• To review recent advancements in minimally invasive image-guided sampling of mediastinal lesions.
• To evaluate the diagnostic yield and accuracy of various techniques.
• To emphasize the benefits of an integrated multimodal approach.

Main Methods:

• Narrative review of literature from major international databases (Medline, PubMed, Scopus, Google Scholar).
• Inclusion of original studies, systematic reviews, meta-analyses, RCTs, and case reports (Jan 2009 - Nov 2023).
• Independent multi-author study selection and evaluation to minimize bias.

Main Results:

• Focus on techniques including EBUS-TBNA, EUS-FNA/FNB, IFB, and nodal cryobiopsy.
• Demonstration of improved diagnostic yield and accuracy with integrated sampling strategies.
• Highlighting the competence-based efficacy of these advanced procedures.

Conclusions:

• An integrated approach combining various minimally invasive sampling techniques is superior for mediastinal disease diagnosis and staging.
• Competent application of these advanced techniques significantly enhances diagnostic outcomes.
• Further research may refine optimal combinations for specific mediastinal pathologies.
